Hi there!
Voltage in a series can be expressed by the following:
In words, the total voltage is equal to the sum of the individual voltage drops in a SERIES circuit.
We can solve for the total voltage:
Answer:
Ф1=295.96Nm^2/C
Ф2=469.73Nm^2/C
Explanation:
The drawing shows an edge-on view of two planar surfaces that intersect and are mutually perpendicular. Surface (1) has an area of 1.70 m², while surface (2) has an area of 4.00 m². The electric field in the drawing is uniform and has a magnitude of 210 N/C. Find the magnitude of the electric flux through surface (1) if the angle θ made between the electric field with surface (2) is 34.0
we have two surfaces where we know angle of surface 1 lets call it
s1= 34.
Therefore to find s2
s2 (the angle from surface 2) we have that
s2=180-(90+s1),
so s2=180-(90+34),
thus s2=56 degrees.
Flux equation reads as Φ=ΕΑ,
where Φ is the flux,
E is the electric field and
A is the surface area.
So with respect to the angles and the figure provided,
we have Φ=EAcos(s).
So we can solve further by writing
. For Surface 1 we have
Φ1=EAcos(s1)=210 x 1.7 x cos 34,
so Φ1=295.96,
approximately to an whole number
Φ1=296 Nm^2/c.
Similarly for Φ2, we have
Φ2=EAcos(s2)
=210 x 4 x cos34=469.7,
thus Φ2=469.7Nm^2/c.
Answer:
Explanation:
The corona is in the outer layer of the Sun's atmosphere—far from its surface. Yet the corona is hundreds of times hotter than the Sun's surface. ... In the corona, the heat bombs explode and release their energy as heat. But astronomers think that this is only one of many ways in which the corona is heated.
The chromosphere ("sphere of color") is the second of the three main layers in the Sun's atmosphere and is roughly 3,000 to 5,000 kilometers deep. Its rosy red color is only apparent during eclipses. The chromosphere sits just above the photosphere and below the solar transition region.
The photosphere is the visible "surface" of the Sun. The Sun is a giant ball of plasma (electrified gas), so it doesn't have a distinct, solid surface like Earth. ... The photosphere is much cooler than the Sun's core, which has a temperature well above 10 million degree
And thats all i know
Answer:
A) To true. he pressure at the bottom of the pool decreases by exactly the same amount as the atmospheric pressure decreases
Explanation:
Let us propose the solution of this problem before seeing the final statements. The pressure increases with the depth of raposin due to the weight of water that is above the person and also the pressure exerted by the atmosphere on the entire pool, the equation describing this process is
P = + ρ g y
Where is the atmospheric pressure, ρ the water density, and 'y' the depth measured from the surface.
Let's examine this equation in we see that the total pressure is directly proportional to the atmospheric pressure and depth
Now we can examine the claims
A) To true. State agreement or with the equation above
B) False. Pressure changes with atmospheric pressure
C) False. It's the opposite
D) False. They are directly proportional
Answer:
The Andrews is A. 90km
Explanation: so far 1cm is equal to 45km on the map. That Means that a unit distance on the map is actually 4, 500, 000units (i.e 45 x 1000 x 100) in real life.
So if 1 cm represents 45km
2cm will represent 2 x 45km which gives 90km.
